WHY HAVE DENTAL IMPLANTS BECOME A MUST???

THE UNDERSTANDING THAT UNLOADED BONE CAUSE MORE BONE LOSS has brought an awareness towards replacing missing teeth and at the same time prevent bone loss.

WHY UNLOADED BONE CAUSE MORE BONE ATROPHY (BONE LOSS)???

MECHANOTRANSDUCTION

Solutions to the problem of atrophic alveolar bone begin with understanding why unloaded bone goes atrophic. Nobody can exactly depict why alveolar ridge goes atrophic after extraction of teeth. Efforts have been made to elucidate the scientific basis for the observation that the integrity of the skeletal tissue has something to do with mechanical usage. Frost has evolved the concept of the mechanostat (Frost, 1996) which he himself proposed as a new paradigm of understanding the mechanical-usage-dedicated message traffic routes between the skeletal tissue and the circumstances in which it is tuned. He argued the mechano-biologic negative feedback mechanisms would adjust skeletal architecture under the control of a subject’s mechanical usage.

Strain-derived fluid flow transduces the strain information to stimulate bone metabolism.

Skeletal tissue has its loading history by dynamic loading which is remembered as a microstrain.
If the strain is too small value, resorption dominates formation of bone tissue and the bone goes atrophic.

If the strain is adequate, resorption balances formation and the bone maintains its volume.

If the strain is adequately high value, formation at last dominates resorption and the bone goes hypertrophic.

If the strain value is high by the overloading outreaching the range of physiological limitation, the strain is accumulated in the bone tissue causing microdamage leading to fatigue failure.
Finally, if the strain value over the limit of yield strength the bone goes spontaneous fracture.

Due to these reasons immediate loading of dental implants will result in functional replacement of teeth and prevent any further bone loss.

PRINCIPLES OF ORTHOPAEDIC BONE SURGERY AND A COMPARISON TO DENTAL IMPLANTOLOGY

Although a number of fractures is still today preferably treated by stabilizing the sites with gypsum, surgical procedures and adequate medical devices have been developed during the last three decades, these include:

1. Screws and plates

2. Intra - bony nails

3. Intra - bony blades

4. Basal implants

Dental Implants and the prosthetic construction of the same resemble the same.

The intraoral situation is special and different from extra- oral applications

1. The mucosal penetration area around dental implants is under constant and vicious bacterial attack.

2. The saliva washes away bacteria as their excretion products and it stabilizes the pH.

3. Jaw bones are not at all prone to osteomyelitic activity

In orthopaedic surgery (knee and hip replacement surgeries) it is taught that immediate loading(using) after plating or screwing will lead to good healing and bone remodelling. The same concept is follwed in immediate loading dental implants.

Primary implant stability refers to the stability of a dental implant immediately after implantation. Its value is derived from a mechanical engraving of the titanium screw implant in the patient's bone tissue. High initial stabilization may be an indication for immediate loading with prosthetic reconstruction. When the healing process is complete, the initial mechanical stability is fully replaced by biological stability. The most critical moment for implantation success is the moment very less initial stabilisation, pending sufficient bone reconstruction supporting long-term maintenance of the implant. Usually this occurs during the 3–4 weeks after implantation. If primary stability was not high enough following implantation, the implant's mobility is high and can cause failure.
